Question:

Are They Subspace of Rn?
Determine whether or not the subsets of Rn given in Problem 1-2 are subspaces. If not, show what required properties they fail to have?
1. Is {(a, b, a - b, a + b) | a, b ( R} a subspace of R4?
2. Is {(a, 0, b, 1, c) | a, b, c, ( R} a subspace of R5?
3. Is {(a, b, a2, b2) | a, b ( R} a subspace of R4?
